Charles Darwin Would Not Be Using Passwords Today

When Charles Darwin said “It is not the strongest of the species that survives but those who can best manage change,” I don’t think he was referring to website passwords. However, I thought this quote was appropriate to where we are now, and how useful passwords are to our lives. Things evolve, and we replace […]

Better Visibility Is Needed When the “Check Cloud” Light Goes On

Remember the old days? When one could look under the hood of a car when the Check Engine light went on? That feels like eons ago, given that cars today basically have a “start button” to fire up the car and get the computer going. The Check Engine light today means a mandatory visit to […]

Network Managers Want Automation for WAN-Based SDN

To date, the majority of software-defined network (SDN) solutions have been focused on the data center. Recently, though, there has been an increase in the number of vendors that provide wide area network (WAN)-based SDN solutions. As is the case with the data center, the term is very broad and means everything from orchestration of […]

What’s the Role of the Application Delivery Controller in a Software-Defined Network?

The topic of software-defined networks (SDNs) has been one of the hottest on this site, or really any site dedicated to networking. Much of the focus of the SDN-centric reports and articles I have seen has been on the disruption of the layer 2/3 network by abstracting control functions up from the physical infrastructure to […]

Shake It Up: Converged Infrastructure Requires IT Rethink

A couple of months ago I attended VCE’s first annual analyst conference. For those that don’t know VCE, it’s a joint venture — primarily between Cisco and EMC, with a bit of funding tossed in from VMWare to round out the offering. VCE acts as both a technical integrator and a professional services firm for […]

State Of School Networking Critical For Students’ Future

Last week the Federal Communications Commission (FCC) approved some long-overdue changes to the E-Rate program.  For those of you not familiar with E-Rate, the program, enacted in 1996 under the name “Schools and Libraries Program”, subsidizes broadband and computer equipment for the K-12 vertical and libraries across America.  The program emphasized connecting low-income and rural […]

Network Functions Virtualization Enables Cost-Effective Route Reflectors

One of the concerns I hear from network managers regarding all things software defined networks (SDNs) is the lack of use cases for the new technology.  It seems the technology promises to solve so many problems that it’s hard to understand where to start.  Network Functions Virtualization (NFV) is no different.  Lots of possibilities, but […]

Internet of Things Shifts Computing From the Cloud to the Fog

Mark Twain is rumored to have once said, “The coldest winter I ever spent was a summer in San Francisco”. And if you’ve ever been to San Francisco any time of the year, you’ll know that one of the distinguishing characteristics of the city is how cool, damp, and foggy it can be.  I’ve been […]

IP Video Surveillance a “Deadly” Application for Network Virtualization

It seems in the technology industry we’re always on the lookout for the “killer application” to take something that’s new and make it mainstream.  The best example of this was, of course, Lotus 1-2-3 and its role in the Windows interface becoming the de facto standard it is today.  After that, the floodgates opened and […]

World Cup Creates a Messi Environment for Network Managers

There’s no question that recreational traffic plays havoc with business networks. Between the PGA Masters, NBA March Madness, MTV Music awards, YouTube, and other events, network managers are always struggling to block recreational traffic. This week, of course, viewers across the globe are using the corporate network to find out how Argentina and Lionel Messi […]
